SCA: security update for open-webui (GHSA-c7wp-3qh5-55pv)

medium Tenable Self-Hosted Container Security Plugin ID 441601

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior
to 0.9.0, the GET /api/v1/channels/{id}/members endpoint only checks membership for group and dm channel
types (lines 467-469). For standard channels — including private ones — there is no channel_has_access
check before returning the member list. Any authenticated user who knows a private channel's UUID can
enumerate all users with access to that channel. This vulnerability is fixed in 0.9.0. (CVE-2026-44559)

Solution

Update the open-webui library and its related packages to version 0.9.0 or later.
